Detection of Hidden Voids in the Giza Pyramids

Groundbreaking discoveries within the Great Pyramid of Giza reveal two previously hidden structures: the ScanPyramids Big Void (SP-BV), identified in 2017, and the ScanPyramids North Face Corridor (SP-NFC), uncovered in 2023. The latter was visualized for the first time after 4500 years using a 6 mm diameter endoscope inserted into block joints. Non-destructive testing (NDT) methods, including muography, ground-penetrating radar, ultrasound tomography, and electrical resistivity tomography, were employed to investigate the pyramid's internal structure without causing damage. These techniques, supported by numerical simulations and data fusion, also detected air anomalies behind the Eastern wall of the Menkaure Pyramid. The findings advance our understanding of ancient construction techniques and the preservation of cultural heritage.
